3. Introduction

4. Introduction • X-CTU software • This is what you need to configure the Xbee modules. • Xbee modules • Series 1(802.15.4), Series 2(zigbee), DigiMesh • XbeeExplorer USB, Xbee Shield

5. Introduction • Xbee Explorer USB • Install the firmware, changing setting

6. Introduction-Xbee • Xbee • These modules use the IEEE 802.15.4 networking protocol for fast point-to-multipoint or peer-to-peer networking • Chip Antenna, Wire Antenna…

7. Introduction-Xbee Shield • Xbee Shield

8. Arduino board + xbee shield + xbee module

9. X-CTU program 을 이용하여 Xbee module 를 설정한다. Setting xbee module

11. Xbee module을 Coordinator, Router/End Device로 설정 Xbee Module Setting

12. Coordinator setting

18. 완료 후 Read 버튼 클릭 후 정보 확인

19. Router, End device • Coordinator 연결을 유지하고 설정 한다. • Coordinator 설정 후 PAN ID 값에 맞춘다.

20. Router/End device

21. Router/End device DL = 0 확인 Write 클릭

22. Xbee setting coordinator Router & end device

26. Xbee Communication Test void setup() { Serial.begin(9600); } void loop() { Serial.println(“hello world”); delay(1000); }

27. Xbee echo server/client Send Data Response

28. Sketch • void setup() { • Serial.begin(9600); • } • void loop() { • while(Serial.available()){ • char getData = Serial.read(); • if(getData == 'a'){ • Serial.print(‘a’); • }else if(getData == 'b'){ • Serial.print(‘b’); • } • } • }

29. a = send data a = recive data b = send data b = recivedata

30. 도전과제

31. 도전과제 • Xbee통신으로 LED를 제어하기 • Coordinator 에서 데이터를 전송하여 Router에서 LED 제어하기 • Ex) “5” 라는 데이터 전송 시 5개의 LED on • Ex) “3” 라는 데이터 전송 시 3개의 LED on • 온도, 조도, 습도 센서 값을 전송하기 • Router 에서 Coordinator 로 전송하기
